snyk@1.1306.3
snyk library and cli utility
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe install hook is a package-aligned, integrity-checked CLI bootstrap, not a demonstrated malicious chain. Network and process primitives are limited to the Snyk wrapper and explicitly user-invoked CLI execution.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
npm postinstall downloads the binary; user invocation of bin/snyk executes it.
Impact
Installs a verified Snyk CLI binary inside the package directory.
Mechanism
verified platform-specific CLI bootstrap and user-invoked execution
AI rationale
The install hook is a package-aligned, integrity-checked CLI bootstrap, not a demonstrated malicious chain. Network and process primitives are limited to the Snyk wrapper and explicitly user-invoked CLI execution.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json postinstall invokes wrapper_dist/bootstrap.js.
- bootstrap downloads a platform CLI binary during install.
- common.js writes the download into wrapper_dist.
Evidence against
- Downloaded binary URL/version/name are fixed by package-generated metadata.
- common.js verifies SHA-256 against bundled sha256sums.txt before rename/chmod.
- The installer does not execute the downloaded binary; bin/snyk runs it only on user CLI invocation.
- No source evidence of credential harvesting, foreign config writes, persistence, or destructive behavior.
